Problem Description
There is a relatively complex HTML fragment (A). If this HTML fragment is embedded into other pages (B, C, D...).
The key to the problem is that there is a lot of JavaScript logic that needs to be processed in the HTML fragment, such as paging, click event response, etc.
For this problem, we use a simple example to illustrate:
"There is a button on the page. Click this button to introduce an HTML fragment. There is a paging button in this HTML fragment."
1. Use IFrame
main page, click a button to introduce an IFrame to the page:
Copy code The code is as follows :
="button" value="Next Page" class="next" />
>
2. AJAX returns page fragments and registers events
Note: We use textarea to simulate the returned HTML fragments.
Copy code
The code is as follows:
由于我们需要在多个页面引用同一个HTML片段，这种方法导致大量事情处理被重复性的拷贝粘贴，明显我们需要将公共的方法提取出来。
3. AJAX返回页面片段，并调用页面片段中的函数注册事件
复制代码 代码如下:
其实我们可以更进一步，完全没必要手工调用这个函数，而是可以在返回的HTML片段中让其自动执行。
4. AJAX返回页面片段，其事件自动注册
复制代码 代码如下:
